This is what I did to bring up the temp in the fridge. THe temp in the garage was in the 40's-50's and I needed it to be 65-70 in the fridge. So, I bought one of those fermentator wraps and taped it into the fridge. Plugged it in and jst kept playing with the temp controller on the fridge to get it to 68F. Works like a charm, and very easy. Hope that helps!
